Syntax: SETUP STYLE style [ { , style | - style } ]...

The script handles only elements with the specified style. Specify a single style, a list or a range of styles. Legal values for the style number are 0-7 (custom line styles are currently not supported). Use variables containing the style values.

For example: SETUP WEIGHT 1,3-5.

This filter ensures that the script only handles elements with the weight 1,3,4,5.
